Application filed August 18, 1914. Serial No. 857,374.

To all whom it may concern Be it known that I, WILLIAM THOMAS 'BROWN, citizen of the United States, residing at Hapeville, in the county of Fulton and State of Georgia, have invented certain new "and useful Improvements in Locomotive-Headlights, of which, the following is a specification.

This invention relates to an improvement in locomotive headlights, and the object is to provide means for throwing the reflection or projecting a shaft or beam of light at an an 1e to the direction taken by the shaft or Eeam of light from the headlight. By such an arrangement it is possible to observe the movements of a train from points or localities where the train is not observable, yet bythe stream of light, it is possible to determine approximately the location of the train, and in case of accident, to take the necessar precautions to prevent the wrecking of t e approachingtrain.

he invention relates to still other novel features of construction and combinations of parts which will be hereinafter more fully described and pointed out in the claims.

In the accompanying drawings: Figure 1 is a perspective view of a reflector showing the invention applied thereto;- Fig. 2is a perspective view'of the secondary reflector older; Fig. 3 is a perspective view showing "the secondary reflector holder applied to a secondary reflector; and Fig. 4 is a plan view of a modified form of secondary reflector; Fig. 5 is a central vertical section. v

A represents the'reflector to which the invention may be applied. This reflector is provided with openings 1 and 2 through which the chimney (not shown) of a lamp projects.- A concave secondary reflector 3 is supported upon the frame, consistin of the central member 4 with arms 5, 5 ra 'atving therefrom. These arms extend to the ed e of the. secondary reflector 3, andthe en of the arms are received in orifices 6 in the peripheral edge of the secondary reflector. At one terminus of the central member 4, a hook 7 is formed, which extends through the opening 1' and engages the reflector A for supporting theframe thereon. A right-angular stripor ortion 8 extends from theflcentral member to the rim 9 of the reflector. I V

In Fig. 4, I have shown a slightly modiand is fastened fied form of secondary reflector, a portion being cut away at one end, as at 10, and opposite to the cut portion 10, a recess 11 is formed. A secondary reflector of this character is some times necessary, so that. the

recessed portion will fit upon the chimney,

but the result obtained is the same. By apstream or shaft of light from the reflector in a direction at an angle to the main stream of light, projected from the reflector.

Iclaim: 1. The combination with a reflector, of a frame removably supported thereon, and a secondary reflector removably mounted'on.

the frame for throwing a stream of H ht at an angleto the stream projected by-t 'e reflector.

2. The combination with a reflector, having openings therein through which a chimney may extend, of a frame mounted on the reflector having an end passing through one of the openings for supporting the frame upon the reflector, and a secondary reflector carried by the frame for throwing a stream of light in a direction at an angle to the stream of light projected from the reflector. 3. The combination with a reflector, of a secondary reflector supported in the reflector for throwing a stream of light at an angle to the stream projected by the reflector, and a flexible frame mounted in the reflector for supporting the secondary reflector, and

adapted to be flexedto accommodate the angle to which the secondaryreflector is to be adjusted.

In testimony whereof I aflix my signature, in the presenceof two witnesses.
